CONCRETE-MOLD.

Specification of Letters Patent.

Patented Jan. 26, 1915.

' Application filed May 4, 1914. Serial No. 836,098.

To all whom it may concern Be it known that I, WILLIAM H. TUOHY, acitizen of the United States, and a resident of Eagle, in the county ofWaukesha and State of Wisconsin, have invented certain new and usefulImprovements in Concrete-Molds; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to the accompanying drawings, and to the letters of referencemarked thereon, which form a part of this specification.

This invention relates to improvements in concrete molds, and moreparticularly to concrete molds adapted to be used in the construction offoundations and Walls of the so-called double wall construction whereinthe wall comprises a plurality of united sections constructed by therepeated use of my device. I

The features of my invention are directed toward the construction of amold that is universal or flexible in its use and is adapted to affordgreater strength and rigidity in concrete construction by permitting asolid thickness of Wall to be formed at the corners or intersections ofwall sections and adjacent to openings in the wall, and by the provisionof a simple attachment to render the mold suitable for the building of acontinuous wall'of the ordinary double wall construction.

The general features of a concrete mold embodying my invention are setforth in a prior application filed by me on the 27th day of December,1912, and bearing Serial No. 808,918.

My invention therefore consists in the matters hereinafter set forth andmore particularly pointed out in the appended claims and illustrated inthe accompanying drawings. in which Figure 1 is a plan View of a form ofmold constituting my invention; Fig. 2 is a View in vertical section,taken on line 22 of Fig. 1; Fig. 3 is a view in side elevation of thesaid mold, with portions broken away; Fig. 5 is a fragmentary view,taken on line 3 --3 of Fig. 1; Fig. 4 is a view in side elevation of theblock adapted to be attached to the mold when used in the constructionof continuous walls; Fig. 5 is a fragmentary plan view, showing themethod of constructing a continuous wall; Fig. 6 is a fragmentary planview, showing the manner of forming a solid corner; Fig. 7

is a sectional View, taken on line 77 of Fig. 6; Fig. 8 is a sectionalView, taken on line 8 8 of Fig. 5, showing the block attached to themold in position for constructing a continuous wall; and Fig. 9 is asectional view, showing a modified construction of my device.

Referring to the drawings showing a preferred embodiment of myinvention, the concrete mold illustrated comprises, in general, twopairs of mold boards 10, 11 and 12, 13. The pairs of mold boards areseparated from each other by a space, and each pair comprises twoupright mold boards arranged to be normally maintained in parallelrelation and spaced apart to form a space therebetween adapted toreceive the concrete for the construction of each of the sectionsconstituting the double wall. The mold boards are preferably constructedof sheet metal and are supported in upright position by means oftransversely extending frame member-s 1 1, 1 1, provided with downwardlyextending arms to which said boards are secured. The arms supporting onemold board of each pair are mounted in fixed relation to the framemembers and the arms supporting the other mold board of each pair arepivotally mounted upon the frame members to permit a limited movement ofthe bar supported thereby for the purpose of attaching the mold board toand releasing the same from the already completed portions of the wall.A manually operated means is further provided in connection with eachframe member for the purpose of simultaneously controlling the movementof the pivoted arms and the mold board secured thereto.

Referring now more in detail to the construction of my device, the moldboards 10, 11, 12 and 18 are arranged with their upper and lower marginsin parallel relation. The spaces between the boards 10 and 11, or 12 and13, of each pair, are preferably equal, and the distance between theinner boards 11 and 12 corresponds with the desired width of the spacebetween the parts of the double wall to be formed by the use of thedevice. The outer mold boards 10 and 13 project, at one end of the mold,a considerable distance beyond the ends of the inner mold boards 11 and12. The space between the ends of the inner mold boards, at the same endof the mold and at the opposite end thereof, is closed by means oftransversely extended members 12, 12 preferably attached to or formed onthe mold board 11, and extending to and overlapping the adjacent end ofthe mold board 12. The transverse members may have the form of removableor detachable gate members, such as are shown in my prior application,but the form thereof illustrated is preferred for use in molds in whichthe two pairs of mold boards are not adjustable with respect to theirdistance apart. The outer mold boards project beyond the inner moldboards a distance preferably about equal to the distance between saidouter mold boards, so that there is formed at one end of the mold arectangular space, which is separated fromthespace between said innerboards by the transverse member 12 The upper margins of the mold boards,by preference, lie in substantially the same horizontal plane. The lowermargins of the outer mold members 10 and 13, however, project somedistance below the lower margins of the inner mold boards 11 and 12, asshown in Fig. 3. vThe frame members. 14:, 1d extend transversely of thesaid mold boards and are spaced a suitable distance for properlysupporting the boards and for operating the mold, one of said framemembers being preferably adjacent to the transverse member 12'" at theshortened ends of the inner mold boards 11 and 12. Each frame membercomprises a rectangular structure consisting of pairs of horizontal bars15, 16, arranged in parallel relation, one above the other, and rigidlyconnected at their ends by means of vertical connecting members 17 thesaid connecting members extending between each pair of horizontal bars15 and 16, and act to hold the said bars at a distance apart to form thespace between them. A plurality of rivets 18 extend through the ends ofthe bars, thus completing the rigid structure of the frames 14:, 14:.

Each of the frame members 1 1, 1 1 comprises a series of vertical arms19, 20, 21 and 22, said arms extending downwardly and supporting attheir lower extremities the several mold boards, there being providedsuitable means for securing saidarms to the outer faces of the moldboards. Two of these arms 19 and 20 are secured in fixed relation to theframe and extend between the upper and lower horizontal bar members 15and 1 6, the same being rigidly held in position by means of bolts 23.The arms 21 and 22 are secured to the frame members in a manner topermit them to. be oscillated through a limited distance,the same beingpivoted to the lower horizontal bar member 16 by means of bolts 21. Thearm 21 projects a distance above the upper bar mem ber 15, whereas thearm 22 terminates between said upper horizontal bar members.

For the purpose of oscillating the boards 10 and 11, respectively, forthe purpose stated, I employ the following members: Rigidly fixed to theframe member 1 1 is an arm 25' which projects above the horizontal barmembers in vertical position. Between 22 through the medium of theconnecting link 27.

The lower ends of the arms 21 and 19, to which are attached the innermold boards 11 and 12 project below the margins of said inner moldboards and terminate in the plane of the lower margins of the outer moldmembers 10 and 13. These end portions are bent inwardly in verticalalinement, with the inner surface of said boards 11 and 12, and areextended below the lower edges of said, boards-to provide, in efiect, aplurality of clamping lugs 19' and 21, the purpose of which will beapparent as I proceed with the description of the operation of mydevice.

One of the outer mold boards, shown herein as the board 13, is providedat its lower margin with a rectangular recess 13 formed by'rabbetingaportion of the board, at its lower margin and at the end thereofextending below the inner mold boards. The recess extends inwardly fromthe outer extremity of the board 13 a distance equal to the distancebetween the outer boards 10 and 13, that is, to. a point oppositethetransverse portion 12 of the inner mold board 11. The width of therecess 13 is equal to the distance which said outer board 13 projectsbelow the inner mold'boards.

The operation of constructing the walls of the so-called double wallconstruction is, as before suggested, accomplished by the repeated useof my device and in the following manner: In Figs. 6 and 7 is shown aportion of a wall 30, already completed, with the mold secured theretoin position to receive the concrete for the formation of a section ofthe wall to be superimposed upon said completed portion, and also inposition to form the junction of two intersecting sections of the wallmeeting at right angles. To secure the mold in position the turn-buckle26 is manipulated so that the movable mold boards 10 and 12 are swung ina direction away from the stationary moldmembers 11 and 13,respectively. By this operation the space between the pairs of moldboards is increased sufficiently to allow the upper portion of thecompleted portion of the wall 30 to pass between the boards. The deviceis placed in position with the lower margins of the outer mold boardsslightly overlapping the outer surface of each wall portion and theclamping members 19 and 21 at the lower extremities of the arms 19 and21, respectively, also overlapping the upper margins of the innersurface of the-wall. By again manipulating the turn-buckle, the movablemold boards are carried inward toward the stationary mold boards,thereby acting to clamp the mold boards to the walls in position to befilled with concrete in the usual manner. The purpose of the clampinglugs willbe now apparent, namely, to provide means for clamping bothpairs of mold boards to both walls and at the same time provide that thelower margins of the inner boards 11, 12 shall terminate at the uppermargins of the walls, so as not to interfere with the reinforcing rodsor members which may be placed in the walls in a manner to extend acrossthe space separating the said walls. Although the mold may be used toform a straight or continuous wall, the form herein shown is moreparticularly designed for the formation of corners and door 7 and windowopenings, whereby a solid wall may be produced at said corners and atthe sides of such openings. As shown in Figs. 6 and 7, the mold isclamped to the wall and in position for forming a solid corner, as abovesuggested. In this position the ends of the outer mold boards 10 and 13project slightly beyond the end of the wall and between said ends isinserted a gate member 31. This gate member may be ofany suitable form,although a piece of board of suitable length and thickness and having awidthequal to the distance between the outer boards is adequate. Thismember is held in position by the clamping action of the outer moldboards and forms an end closure for the mold. In this position of themold the recess l3 (Fig. 7) receives the intersecting. portion of thewall, thus permitting the end of the outer mold board 13 to extend overthe said intersecting portion without interfering .with the properpositioning of the mold board in horizontal relation to the wall. Themold is now ready to receive the concrete, which is placed between theinner and outer mold boards and within the space beyond the ends of theinner mold boards formed by the outer moldcboards and the member 31. Thetransverse wall portion 12 thus acts to form an end wall for the spacebetween the inner mold boards so that the corner formed by theintersecting sections of the wallf30 may be of solid construction by theomission of the space which is ordinarily formed throughout the straightportions of the wall. hen the concrete is sufficiently hardened, themold may be released by manipulating the turnbuckle in the mannerindicated and the mold again secured to the wall in position .to formthe next section which 1n th1s 1nof a width substantially equal to thewidth of the space separating the walls. The length of the block issubstantially equal to the distance from the transverse member 12 of theinner mold member 11 to the extremities of the outer mold members 10 and13. The upper surface of the block is provided with an inclined orsloping surface 33, extending substantially throughout its length, asshownin Fig; 4. The rear portion of said block is provided with anupwardly extending arm 34 rigidly attached to the rear surface of theblock, the same being. inclined slightly rearward (Figs. 4: and 5) andprovided at its upper end with a hooked portion 35. Upon the lowersurface of the block is provided a downwardly integral with the block,and the end surfaces of which are flush with the side faces of theblock. As shown in Figs. 5 and 8 of the drawings, the block is attachedto the mold by means of the arm 34, which. is adaptedto engage theadjacent frame member 14 by means of the hooked extremity 35 of the arm,which enters downwardly into the space between the lower horizontal barmembers 16,16 of said frame. In this position the block abuts at itsrear surface against. the transversemember 12 and extends therefrom in adirection toward the end of the -mold, its lateral surfaces beingparallel to the outer mold boards 10 and 13.

When attached to the mold the lower surface ofthe block lies in theplane of the lower margins of the inner mold boards, and the projection36 extends downwardly below the upper margins of the walls 30, with itsside faces in contact with the inner faces of .said walls, into thespace separating said walls. It'is obvious that the said block serves asan extension of the inner mold boards, so that, when the same is in use,the entire length of the mold may be utilized in the construction of thestraight parts of the double wall. The projection 86 beforeextendingprojection 36, that may be made Width, and a transverse memberextending between the ends of said inner mold boards, at the same end ofthe mold.
